. TIRE .ARMOR.

Application filed June 11, 1925. Serial No. 36,472.

To aZZw/lo-m it may concern: Be it known that I, GEORGE a citizen of the United States, residing at Ontario, in the county" of San Bernardino and Stateof California, have invented certain new and useful Improvements in Tireprovide a construction which is simple and inexpensive, yet is exceptionally durable and advantageous, will make practically no noise even when running on hard pavements, and will be substantially proof against skidding.

With the foregoing inview, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure l is a perspective view showing the application of the armor to a tire casing.

Figure 2 is an enlarged sectional view through a portion of the armor cut in a circumferential direction.

Figure 3 is a plan view of one of the sections of the armor.

Figure 4 is a plan view of one of the metal straps which are secured to the outer sides of the channel-shaped sections of the armor andbent to form hooks for connecting said sections. 1

Figure 5 is an edge View partly in section, of the strap shown in Fig. i,

In the drawing above. briefly described, the numerals 1 designate a plurality of cir cumferentially extending, channel-shaped sections of the armor, each stamped from a single metal plate and each having an enlarged end 2 formed with a: central notch 3, while at the opposite end, each section 1 is formed with a transverse slot .4. Obviously, the enlarged ends 2 of the numerous sections are adapted-to receive the other ends of the next adjacent sections, as shown. Secured upon the longit 'dinal, central portion of each armor section 1, is a metal strap 5, one end of which isdisposed at the inner edge of the slot 4;,while its other end.-

is received in the notch 3, the last named end having a thinned extension 6 which isbent ti form a hook bill, this bill of each section oi the armor passing through theaslot 4 of p the next adjacent section, as shown in Fig. N. CHILDERS,

2. l\.[oreover, it will be seen from this view.

that the hook bills 6 of the several armor sections lie against the inner sides of said sections and'are of substantially negligible thickness, to overcome danger of injuring the tire casing around which the device is used. Preferably, one tapered rivet 7 is used to fasten each hook hill 6 and the contiguous end portion of the strap 5 to one end of each armor section 1, while a similar rivet strap to the armor. By tapering the rivets in the mannershown, they will not loosen as the straps 5 and the outer ends of the rivets become worn. 3 f' p V v Not only do the straps 5 assist in connecting the numerous sections of the armor, but they stiffen the central circumferential portions of said sections and jointly form substantially a continuous tread band, and this band assists materially in preventing skid ding. Moreover, by having this band of substantially continuous form and free of any large pro ections, the armor is almost noiseless, even when runnlng on paved streets.

8 is used to secure the other end of the In practice, thenumerous sections of the 1 armor, are connected in a sufficiently loose manner topermit them to relatively move to a slight extent as the tire yields so that al-" though such tire is efiectively shod with a metal, its resiliency'is not impaired.

When applying the device, it is of course necessary-todefiate the tire and the latter is usually removed from the rim. hen the device is applied howeverandthe tire reinflated, the tire casing snugly engages the armor and is held against any slipping or chafing thereon, by the internal pressure, the armor being made a trifle smaller than the casing, in order that this snug fit may be obtained. 5

Excellent results are obtainable from the i details disclosed and they are therefore pref erably followed, but within the scope of the invention as claimed, slight modifications may be made.

' section, the enlarged end ofeach section having a central notch while the other ends of said sections are formed with slots with which the notches register, and a plurality of central circumferentially extending metal straps secured one to each of said sections, the strap of each section passing at one end through the notch of such section and having a hook bill Which passes through the slot of the next adjacent section, the hook bills of the numerous sections lying flat against the inner sides of said sections, said straps forming substantially a continuous tread and non-skid band around the armor. 10

In testimony whereof I have hereunto afiixed my signature.
